I had my fuel injection system cleaned at Big 'O Tires. This my first set (just put them on). I just don't know what is up. My truck has been maintained properly as far as changing out things. What I don't know is what do do next. There is no codes. But it does misfire/hesitate/backfire when accelerating. Nothing seems wrong when at an idle or while in park and reving the engine up.

I am thinking that the VCT Solenoid could be the issues after reading up on it. I have replaced both cam shaft sensors, all 8 coil packs today. Anything else I should try? EGR sensor?

This is increasingly frustrating! No codes! Just a hard hesitation that jerks the truck and sounds like a back fire or poping noise up front. When I let off the truck runs great. If I accelerate it does the jerking and back firing. Rev it in park, nothing. Rev it in neutral, nothing. Anything more on if this could.be caused by the VCT Solenoid?
